CNG stoves

Hi, I searched CNG stoves on the forum = very few info.
Are these stoves safe? I read somewhere that CNG is hard to find and super explosive?
Thanks

Re: CNG stoves

I don't think there's much you can learn about LPG / propane that does not apply also to CNG.

Many devices don't even need to resize the jet?

Yes dangerous, in the same way as gasoline / petrol.

Safe as the owner and their precautions.

Best to do without if practical.

Re: CNG stoves

CNG is lighter than air as opposed to propane being heavier than air. So it's much safer than propane considering if you have a small leak no build up in the bilge is possible.

Re: CNG stoves

CNG is harder to find than propane but you can get an adapter for tanks to get it filled at the auto filling stations me at for cng vehicles. Also places that fill tanks for forklifts might have it. But usually those are all propane too.

Re: CNG stoves

CNG is increasingly common as a fuel of choice for fleets; buses, service vehicles, etc. however it can be very difficult or inconvenient to get a canister refilled. That is unfortunate because CNG is much safer than propane (which is readily available everywhere). CNG is lighter than air. So, if there is a leak, CNG floats harmlessly away while propane sinks and collects in the bilge where it could be ignited and explode. Because CNG is so much lighter than propane, it must be stored at higher pressures (2500 psi versus 40 psi or so for propane).

Re: CNG stoves

Plenty of CNG fill places in coastal New England. Plus big distributor in RI. It is more expensive then propane but what's the value of your life?

IMO its like gas vs diesel on a boat. One explodes the other not so much.

Fueling stations listed here: https://www.afdc.energy.gov/fuels/na...arest?fuel=CNG
You will need the same fitting found on CNG cars. https://www.weh.us/weh-receptacle-tn...rs-series.html

Re: CNG stoves

While you're waiting for that,

(might be a while, since very few regular cruisers anywhere in the US use CNG anymore, much less that one location)

it is likely that Dept of Energy website / app is 100% complete about CNG retailers, since they were very motivated to try and increase its market acceptance.

In case you thought the local CNG-users may have additional sources.

But maybe they will, I'm just speculating. . .

Re: CNG stoves

Thanks John, you are probably right but does not hurt to ask. Many DOE stations don't want to bother with a tank refill. My tank should last another year or two.
